307-mph electric car breaks the battery powered land speed record
They pushed 245mph to 307. That's a huge accomplishment.
The ICE record is 400mph and 45 years old!
Just thinking: it would "only" take 4 PEMs, 4 Tesla motors (the electricity-to-motion converters, not the company!) and 12kWh of A123's (which can discharge at 60C) installed in a Veyron to match the Veyron's ICE and get to 250mph. Oh, and replace the gearbox with a 1:4 or so gear ratio on each wheel.
Considering all that, it's quite a radical racecar they used to get to 307mph, just 23% above the Veyron's top speed.

0-60 in 10 seconds!
12kWh is 43200 kWseconds
If you pull 720kW you only get 60 seconds of juice.
Its going to be tough getting to 250 mph in 60 seconds, especially without a transmission.
However on the flip side: you can make a much more aerodynamic car than the Veyron, because you arent turning 70%-80% of the energy you consume into heat - heat you need to dump via radiators.
No frunk. Dealbreaker.
